Stock, turnover and functions of carbon in heavily weathered soils under lowland rainforest transformation systems (A04)

• Subject Area: Soil Sciences
• Term: from 2012 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 192626868

In the 2nd phase the project will reveal the main processes of C stock decrease and soil degradation: erosion and mineralization of soil organic matter in a broader ecological context. The project will focus on the differences of stability of remaining soil C between intensive plantations. New approaches including incubations, C fractionation, isotopic composition, pyrolysis and 3D fluorescence will be applied. The project will strongly contribute to the overall goals of the planned CRC by providing data on stocks, forms and processes of C transformation after forest conversion to plantation by focusing on the stability of C and its availability for soil microorganisms. The project is closely integrated into other projects of groups A, B and C investigating changes in the belowground system with focus on soil fertility, productivity, ecosystem stability and modelling perspectives.
